How much Bac Water to get?

[RoachForLife19]

Approx how much bac water do most people use per 100IU kit would you say? Im getting 500iu, and prolly more down the road but dont want to order way too much if Im never going to use

Thanks

you could do the math, but it's only 5 bucks for 30ml

I put 1ml BW per vial. 50 vials is 50ml. Get a couple of 30ml vials and you're set to go.
